Two dimensional fabrics of woven graphite tows represent the structural backbone of present aerospace composite parts. These fabrics are comprised of 0 and 90 degree system of yarns, X and Y respectively. They are flat planar structures produced on conventional weaving looms. As advanced composite materials find use in more critical aircraft components, more stringent requirements are placed on reinforcing yarns and fabrics. Textile loom design has not kept pace with the use of composite materials. There has never been a loom designed specifically for weaving high modulus (graphite, ceramics, etc.) yarns into fabrics. The overall objective of this program was to advance the level of materials and processing techniques for high temperature polymeric, metal matrix composites and ceramic matrix composites. The major emphasis of this work was directed towards developing a composite reinforcement fabrication system, specifically, a machine design study focused on designing a loom or loom adaptation capable of integrally weaving four (4) or more directions of yarn (multi-angular weaving).
